With the rapid development of domestic industrial economy, the output of industrial sludge keeps rising, bringing increasingly severe environmental pollution. To address the treatment and disposal of industrial sludge, various industrial sludge dryers have been launched in the market. What are the equipment characteristics of industrial sludge dryers? This article gives a detailed explanation.
1. Volume & weight reduction, dewatering and drying. Industrial sludge features high moisture content and high viscosity, making its disposal difficult. To accelerate dewatering and drying of wet sludge, the industrial sludge dryer adopts high-temperature heat transfer technology. Combined with internal crushing devices and material lifting & guiding system inside the cylinder, it improves mixing and contact between sludge and hot air. Moisture in wet sludge vaporizes and evaporates continuously under heating to realize sludge dewatering and drying. Normally, the equipment can dry high-moisture wet sludge to the moisture content required by customers in a single pass, greatly reducing sludge weight and volume and facilitating subsequent transportation, storage and resource reuse.
2. Energy-saving, environmentally friendly and wide application range. The industrial sludge dryer supports diverse heat sources, including coal, fuel oil, natural gas, steam, biomass pellets and boiler flue gas. Users can select suitable heat sources according to actual production demands. Besides, the whole industrial sludge drying production line is tightly sealed and equipped with sound thermal insulation structure, which effectively reduces heat loss inside the cylinder, improves thermal efficiency and cuts operating costs. No flue gas or dust leaks from the cylinder during operation, minimizing impacts on the working environment.
3. Waste gas discharge up to standards. To handle waste gas generated during drying, a professional dust removal unit is installed at the tail of the industrial sludge dryer. It filters, purifies and removes dust from flue gas produced in operation. The treated gas will be discharged after meeting emission standards to mitigate environmental impacts.
4. Improve the economic value of sludge. Dried sludge has uniform moisture and low water content, easy for transportation and storage. Moreover, the calorific value of sludge is increased. It can be used for producing cement, ceramsite and bricks, or co-fired with coal for power generation, bringing economic, environmental and social benefits for enterprises.
